APPARATUS FOR MAKING AND BURNING GASEOUS FUEL.

SPECIFICATION forming part of Letters Patent No. 349,228, datedSeptember 14,1886.

Application filed April 2, 1386.

To all whom it may concern.-

Be it known that we, JOSEPH LOOKE and SOLON O. RICHARDSON, Jr.,respectively of Glenwood (Medford) and WVakefield, both in the county ofMiddlesex and State of Massachusetts, have invented certain new anduse-' ful Improvements in Apparatus for Making and Burning Gaseous Fuel,of which the following is a specification.

This invention has for its object to provide a simple and efficientapparatus in which oil may be vaporized and burned and steam superheatedand mingled with the flame of the vaporized oil, thereby producingperfect combustion and a high degree of heat at a small expense.

The invention also has for its object to provide convenient means forregulating the degree of heat by either concentrating or diffusing it.

To these ends our invention consists in an apparatus which in itssimplest form includes, first, an externally heated oil vaporizingchamber or retort having means for the discharge of oil in jets againstits inner surface, the oil being vaporized within an externallyheatedretort, and orifices for the escape and combustion of the vapori zedoil; and, second- 1y, a steam-pipe communicating with a suitablesteam-generator and extending for a portion ofv its length substantiallyparallel with and in close relation to the orifices in the vaporizing-rctort, whereat the vaporized oil is discharged and consumed. Saidsteam-pipc is highly heated by the heat supplied by the apparatus, sothat the steam therein issuperheated. The steanrpipe is provided withoritices or nozzles for the escape of the steam in jets coinciding withthe jets of flame from the ignited.

Our apparatus, as we prefer to organize it, includes two oil-vaporizingretorts and two independent steam-pipes arranged side by side, eachchamber and its accompanying Serial No. 197,590. (No model.)

steampipe being preterably adjustable independently of the other, sothat the heat produced by the two sets may be either concentrated ordiffused by decreasing or increasing the distance between the sets, allof which we will now proceed to describe.

Of the accompanying drawings, forming a part of this specification,Figure 1 vrepresents a perspective view of an organized apparatusembodying our invention, the chambers or retorts being partially brokenout to show the perforations in the oil-pipes which lead into the saidchambers. Fig. 2 represents a transverse section of the same taken onthe dotted line 02.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, A A designate two iron chambers or retorts placed sideby side at the required distance apart, and made, preferably, in theform shown in the drawings, the said retorts being preferably supportedupon sliding blocks a a, adapted to move in ways or guides a a by theoperation of levers B, one for each chznnber. These lovers are fulcrumedat b, and are connected bythe rods 1/ to each of the chambers or retortsA A. The movement of these levers in the one direction or the otherserves to so move the chambers or retotts as to place them closertogether or farther apart, and thereby either concentrate or diffuse theheat, as circumstances may require. Each chamber or retort is providedperforations or openings, 1), and at one end with a hole, 71, into whichis passed a perforated pipe, G, the said pipes G extending from one endto the other of the chambers or retorts on the inside, and beingconnected on the outside by the elbows c c to the short pipes O C. Theseshort pipes G 0, having their free ends inclosed within the T-couplingD, are capable of being moved within the said T- coupling when thechambers or rctorts are moved toward or from eachother. The pipe E,leading from a reservoir or source of supply of oil, (not shown in thedrawings, is joined to the T-eoupling D, through which and the pipes O 0oil is, passed to the pipes O 0 through the perforations or openings, inwhich it is discharged against the heated inner sur-' in the directionof its length with a series of faces 01' the ehambers or retorts A A.where it becomes vaporized. The vapor passes out through the openings 1.and is ignited at said openings the flames rising from the ehambers orretiorts. as shown in 2.

Innnediately in front (11' the ehambers or re torts A A. and pret'erablyabout on a level with the openings p in them. are plaeed two pipes, F 1one for eaeh ehamber or retort. and eaeh being provided with a series ofopenings. p. eorresponding in number with the openings 1) in thechambers or retorts. These pipes F 1 are joined by the elbowsffto thepipes G t1. whieh praetieally surround the ehambers or retorts A Aandeonneet with the steanrsupplv pipes H H. whieh lead from a suitablesteam-generati1r. The steam passing through said pipes beeomessuperheated and eseapes through the openings 1). said openingseoineiding with the openings 1), so that the jets ol' steam interseetand mingle with the jets ot'flame from the retorts, as indieated in Fig.2.

As a means ot' heating the retorts A A before the apparatus is inoperatiomwe provide pipes I 1 below eaeh ot'the retorts and extendingalong the t'ull length ot' the latter. said pipes being shown in thedrawings as provided with a series 111' small pert'orations or jets, j.At one end these pipes are elosed by eaps. plugs. or other suitablemeans. and at the other ends they are eonneeted to pipes l l. whieh leadfrom small tank K. eontaining oil or petroleum. the supply of oil orpetro leum to the jets or pert'orationsj in the pipes 1 I beingregulated by the valves 1 in the pipes 1' I.
